Description
Technical field
The present invention relates to be used to make the stamp of tissue paper or non-woven fleece material and the method and apparatus of the embossed multi-ply width of cloth.The invention still further relates to the stamp and the embossed multi-ply width of cloth of tissue paper or non-woven fleece material.
Background technology
To tissue paper or the non-woven fleece width of cloth carries out embossing and stamp is common.Embossing is that a kind of mode and its of the bulk density that improves paper also makes paper have three-dimensional structure, thereby has improved the absorbent properties and the aesthetic property of tissue product.Embossing further can be the mode that two or more tissue plies are laminated together, and embossing position above that forms the mechanical engagement of synusia.Embossing often and gummed make up with the laminated thin cotton paper layer.This scheme is for example at US 3,414, and is open in 459, wherein shows through embossing and bonding process are made up and the laminated thin ply of paper.Embossing is usually alleged " pin joins (foot-to-foot) to pin " form, and according to this form, the rising projection of the tissue ply of embossing is engaged with together.US 3,867, and 225 also disclose the embossing and the gluing technique process of combination, but wherein embossing is usually alleged " nested " form, and according to this form, the recess of opposite layer is inserted in and is joined to the rising projection of a tissue ply.
The said tissue paper or the non-woven fleece width of cloth are normally used for making the product such as toilet paper, family expenses towel, handkerchief, face tissue, tissue, wiping thing paper and napkin.
Often carry out the stamp of tissue product from reason attractive in appearance.Decalcomania can be any pattern, comprises more or less continuous lines, line segment, point, trade mark, sign, symbol, virtual portrait etc.Can adopt one or more colors.A kind of usual manner of embossing and stamp multi-layer thin tissue product is the embossing and the lamination of first complete layer and carries out stamp subsequently.This method will cause printing inks to be on the product outside.Because product surface is no longer put down because of embossing, the printing ink transmission is no longer accurate, especially has the zone of recess because of embossing at product.
According to alternative approach, at first carry out the stamp of tissue ply, this tissue ply and another tissue ply obtain embossing and lamination subsequently.The defective of this method is that printing ink does not always become dry fully before embossing, thus the danger that exists stamp to be besmirched.Tissue ply also can bear local deformation on the embossed area, and this makes that printing area is out of shape.
US 5,339, and 730 have instructed a kind of method of processing the product with two or more layers.Ground floor obtains embossing on being in first knurling rolls and obtains stamp subsequently.The second layer obtains embossing and applies adhesive to this layer through second knurling rolls.After this these two layers connect into assembled web may, make that the stamp on the ground floor is positioned on the layer 2-oriented side.Printing ink and adhesive are applied on the different layers thus.
If printing ink and adhesive are applied on the different layers, then when printed layer one is looked assembled web may sideways, printing quality is best.Adhesive helps to reinforce the embossing of another layer.Therefore the embossing that is applied in that layer of adhesive looks than is printed the embossing better effects if of that layer, so when the second layer one is looked assembled web may sideways, the embossing effect is best.Thereby the user of product sees stamp or embossing with best mode.
Visual appearance has become more and more important attribute for tissue product.It is played an important role when client and/or user select his/her product.Therefore it is quite important to process the product with good visual outward appearance.
Summary of the invention
The purpose of this invention is to provide a kind of tissue paper or the stamp of non-woven fleece material and method and apparatus of the embossed multi-ply width of cloth that be used to make with good visual outward appearance.The invention still further relates to the tissue paper with good visual outward appearance or the stamp and the embossed multi-ply width of cloth of non-woven fleece material.The said stamp and the embossed multi-ply width of cloth comprise two, three, four or more a plurality of width of cloth shape material.
Owing to, therefore need not to adopt complicated machine or complicated control system just can realize aiming at and keep through making first width of cloth shape material keep being in carrying out embossing, stamp on first knurling rolls simultaneously and apply adhesive realizing aiming at accurately maintenance.
Said method comprising the steps of:
Carry out embossing with first width of cloth shape material in-the roll gap between first knurling rolls and counter roller (counter roll) and form one group of embossing thus;
-when said first width of cloth shape material still was on said first knurling rolls, first group in the said embossing group of said first width of cloth shape material applied first printing ink with first color;
-when said first width of cloth shape material still is on said first knurling rolls, second group's applying adhesive in the said embossing group of said first width of cloth shape material;
-when said first width of cloth shape material is on first knurling rolls, make said first width of cloth shape material and second width of cloth shape combination of materials to form the multilayer width of cloth.
In general, group has some elements of another group (being called as hyte) but does not have any group that goes up the element that hyte do not have.Group can also have all elements in the last hyte.In the present invention, last hyte comprises all embossing that produced by first knurling rolls, and is called as the embossing group.Group in this embossing group comprise in these embossing partly or entirely.
Through in stamp, adhesive coating and anabolic process, keeping first width of cloth shape material to be on first knurling rolls, supported from behind while printing ink of embossing and adhesive are applied to the end face of embossing.Supporting prevents subsides.Printing ink and adhesive are positioned in the embossing, have strengthened the effect of embossing thus, thereby form very good visual effect.To prevent that also the embossing that obtains gluing together from subsiding backward in product.The embossing of gummed will help product under dry and moisture state, all to keep its bulk density.
Term " embossing that the obtains gluing together " meaning is that embossing has coating adhesive above that.Term " gummed " is used to apply adhesive.
Said method can also keep stamp and sudden strain of a muscle to close being in absolute aligning.The danger that any material elongates or is out of shape with any other mode between stamp and gummed can not take place.
The stamp of the preferred printing ink of execution earlier is applying adhesive again.Through this order, avoid taking place the danger of adhesive contamination printing cell.Yet this order can be carried out through other modes, just at first applying adhesive and stamp afterwards.
In the said embossing group that the embossing of the stamp of first group can form in the embossing step all or the embossing of some.The embossing of gluing together of second group can be all or the embossing of some in this embossing group.Usually, first and second groups in the said embossing group overlap at least in part, but they can also be complementary, for example do not have any shared embossing.At least a portion of preferred group overlaps, thereby forms the visible combinations effect of adhesive and printing ink.At last, the width of cloth of combination can comprise four kinds of embossing thus: do not have adhesive or printing ink, only obtain the embossing of stamp, only obtain the embossing of gluing together and being glued together and the embossing of stamp.Product through said method manufacturing can also comprise, two or three the embossing that belongs in the above-mentioned type, as long as at least some embossing obtain gummed, some obtain stamp.
And a part of embossing in the said embossing group can obtain gummed or stamp.Therefore, first group can comprise all embossing in the said embossing group, but printing ink only is coated on the part of said embossing.Equally, second group can comprise all embossing in the said embossing group, but adhesive only is coated on its part.Simultaneously in this case, ink logo can overlap complementary or at least in part.
It also is feasible that first group in the said embossing group has some embossing that are coated with printing ink fully and some embossing that part is coated with printing ink.In the same manner, second group can have some embossing that are coated with adhesive fully and some embossing that partly are coated with adhesive.
Adhesive can be that perhaps it can be the colored adhesive with second color to conventional colourless adhesive.Common second color is different with first color.Preferably, adhesive is the colored adhesive with second color, between adhesive and printing ink, to produce the visible combinations effect.Adopting second color to replace having to increase extra printing cell also is usual manner.
Said method is further comprising the steps of; Before each width of cloth shape material is made up; When first width of cloth shape material still is on first knurling rolls in the additional coating element, additional color is applied to as printing ink or colored adhesive at least one the additional group in the said embossing group of said first width of cloth shape material.In the same manner as described above, keep on first knurling rolls aiming at through keeping first width of cloth shape material to be in.Can increase the many printing ink or the adhesive of aequum.The diameter that increases first knurling rolls can provide the space for additional increase unit.
When adopting many colors, preferably their are solvable each other mixed.Solvable mix is not limited to printing ink and dissolves each other mixed mutually physically with adhesive.Opposite term " solvable mixing " is understood that how relevant by sensation with combined color in a broad sense.If a plurality of colors are miscible, then combined color will have the other shade except that primary colors.
If adopt conventional colour printed color-yellow, cyan and reddish violet, any shade in the colour triangle original then almost can be provided.
In one embodiment, apply printing ink through the aniline stamp.Can also replace the similar device applying adhesive of printing ink through adopting adhesive.
First and second width of cloth shape materials can obtain individual processing before combination.They can be for example when wetting, in the drying course of wet stock and/or under drying regime, be applied on the three dimensional pattern structures that is arranged on the material.These processing are included on the fabric of patterning and form paper, in paper machine, make paper (for example TAD paper) simultaneously.They also are included in any type of precreping that forms before the combination of materials.Material can also stamp has independently decalcomania or is coated with chemical substance.

The specific embodiment
Fig. 1 representes to be used to make the stamp of tissue paper or non-woven fleece material and the device of embossed web.First width of cloth shape material 1 obtains carrying through the roll gap 6 between first knurling rolls 4 and the counter roller 5.First knurling rolls have with this width of cloth shape material on the corresponding protuberance of required embossing.The conventional material that is used for knurling rolls can be a steel, and it can have chromium coating.Alternatively, knurling rolls can be by processing such as the polymer of hard rubber, hard rubber or plastics.Often change embossed pattern if desired, then preferably have the system of quick replacing knurling rolls, for example adopt embossed sleeves, matrixes for embossing or device for opening and can mention the taking-up knurling rolls at an easy rate.
Counter roller 5 can be processed by for example rubber, steel or paper.If material is steel or paper, then the girth of the counter roller 5 and first knurling rolls 4 preferably should equate or about equally, perhaps the multiple that girth should be another girth.If material is modal rubber, then preferred girth with counter roller is chosen as and makes it supporting with the smoothing wearing and tearing with the girth of knurling rolls.
When first width of cloth shape material 1 passes roll gap 6, first width of cloth shape material 1 will with the corresponding zone of the protuberance of first knurling rolls 4 on be out of shape.Protuberance produces the embossed pattern that comprises one group of embossing, and wherein the embossing on the width of cloth shape material reflects the protuberance of first knurling rolls.
Fig. 2 a be according to the embodiment of the present invention first width of cloth shape material through the plane after the roll gap 6.In this example, show the decoration element of colored form.Said flower comprises three embossing of first width of cloth shape material, promptly forms the embossing 203 at the center of the embossing 201 of stem, the embossing 202 that forms petal and formation flower.Each embossing is corresponding with the protuberance of first knurling rolls 4.
In on being in first knurling rolls, first width of cloth shape material obtains stamp through graining roll 11 in stamp roll gap 12.Printing cell 10 comprises ink cavity, anilox roll (anilox roll) and graining roll 11.Can adopt ink storing device (fountain) to replace ink cavity.In illustrated embodiment, graining roll 11 carries its printing ink with first decalcomania.Preferably form pattern by this way, that is, it is supporting with embossed pattern at least in part, and just printing ink is printed on the top of at least some embossing.First group of said embossing group is formed in the embossing that obtains stamp subsequently.In this embodiment, have no printing ink being imprinted between each embossing on the width of cloth shape material.The girth of the graining roll and first knurling rolls then preferably should equate or about equally, perhaps the multiple that girth should be another girth.Can also form pattern through newspaper page or leaf (report).Knurling rolls then have a plurality of newspaper pages or leaves around its girth.The newspaper page or leaf is the repeat length of pattern, just after the length of a newspaper page or leaf, occurs same pattern once more.Therefore can form supporting between decalcomania and the embossed pattern through adopting equal newspaper page length degree.Girth can for example be arranged such that then the girth of graining roll is that the girth of two newspapers page length degree and first knurling rolls is five newspaper page length degree.Certainly, can adopt any integer newspaper page or leaf.Can also make decalcomania and embossed pattern supporting through the rotary speed of regulating them, make their commentaries on classics have the identical time, the time that makes a roller one change be the multiple of another roller or makes any newspaper page or leaf all complement one another.
In the alternative, printing ink is all carried on graining roll 11 whole surfaces.1 of first width of cloth shape material will be printed on the top of all embossing.First group of embossing group in this case comprises all embossing.Usually, have no printing ink being printed between each embossing on the width of cloth shape material, because material only contacts with graining roll 11 in embossing place in stamp roll gap 12.In another embodiment, graining roll 11 its surperficial certain proportions are covered by printing ink.This ratio is identical on whole graining roll surf zone.Can cause some embossing to obtain the part stamp like this.If knurling rolls 11 carry printing ink with certain proportion on whole surface or from the teeth outwards, then the girth of the graining roll and first knurling rolls can be selected independently of each other.
Fig. 2 b representes the decalcomania on the graining roll 11.The decoration element of the embossing shown in decalcomania and Fig. 2 a is partly supporting.The stem that printing area 210 is promptly spent is corresponding with embossing 201, and just printing ink is imprinted on the top of embossing 201 in stamp roll gap 12.In an identical manner, the promptly colored center of printing area 211 obtains stamp at the top of embossing 203.First group in the embossing group comprises embossing 201 and 203.
In embodiment shown in Figure 1, first width of cloth shape material remains on first knurling rolls 4 and is transported to the roll gap 22 between first knurling rolls 4 and the adhesive application roll 21.Adhesive application unit 20 comprises adhesive chamber, anilox roll and adhesive application roll 21.Can adopt storage liquid roller (fountain roll) to replace the adhesive chamber.Adhesive application roll 21 is carried its adhesive with pattern of adhesive.Can form pattern through such mode, that is, it is supporting with embossed pattern at least in part, and just adhesive is coated in the top of at least some embossing.The embossing of having glued together then comprises second group in the embossing group.In this embodiment, have no adhesive to be coated on the width of cloth shape material between each embossing.With and preceding text the described same way as of graining roll 11 are formed supporting between pattern of adhesive and the embossing.Adhesive application roll can be the aniline graining roll, and it carries adhesive rather than printing ink.
In the alternative, adhesive application roll 21 is carried adhesive on whole surface.First width of cloth shape material then will be comprised all embossing by the gummed and second group on the top of all embossing.Usually, have no adhesive to be coated on the width of cloth shape material between the embossing, because material only is in the position contact adhesive application roll in the roll gap 22 in embossing.In another embodiment, its a certain proportion of surface of adhesive application roll is by adhesive coverage.This ratio equates on whole adhesive application roll.Cause some embossing to obtain the part bonding like this.If adhesive application roll is carried printing ink on whole surface or from the teeth outwards with certain proportion, then the girth of the adhesive application roll and first knurling rolls can be selected independently of each other.
In illustrated embodiment, can adopt colored adhesive.This point is especially favourable for the embodiment that adopts the adhesive application roll 21 of carrying pattern of adhesive.
Fig. 2 c representes the pattern of adhesive of adhesive application roll 21.In this example, pattern of adhesive forms petal 221 and stem 220.Adhesive is sent to embossing 201 and 202.In embossing 201, adhesive is coated on the printing ink that in stamp roll gap 12, has been printed.In embossing 202, adhesive directly is coated on first width of cloth shape material.Second group of embossing group comprises embossing 201 and 202.In illustrated embodiment, first group of the embossing group that in roll gap 12, is printed is different with second group of the embossing group of in roll gap 22, being glued together.

3, preferably be lower than 0.30g/cm
3, more preferably at 0.08g/cm
3-0.20g/cm
3Tissue paper can crease or non-creasing.Crease and under moistening or drying condition, to accomplish.It can also obtain shortening through the quick conversion (rush transfer) between the for example alleged usually fabric of any other method.
The fabric that is included in the tissue paper mainly is the pulp fibres from chemical pulp, mechanical pulp, thermomechanical pulp, chemimechanical pulp and/or chemical thermo-mechanical pulp (CTMP).Fiber can also be a recycled fibre.When using pulp fibres, its supposition comprises all dissimilar pulp fibres that in tissue paper is made, adopt usually.Can also adopt other slurries of cellulose fibre, for example ramie, flax and jute of cotton linter, bast cell for example, straw pulp, bamboo pulp, bagasse, sisal hemp, straw and hemp.Tissue paper can also comprise the fiber of other types to strengthen, for example the intensity of paper, absorbability or pliability.These fibers can for example polyolefin, polyester, polyamide etc. be processed by regenerated cellulose or synthetic material.
Non-woven material be defined as orientation or free directed fiber through friction and/or in gather and/or artificial of adhesive bond, the width of cloth or batt the product of getting rid of paper and weaving, braiding, synthetic tuft, stitching (combination have combine yarn or fibril) or forming through wet-milling felt system (no matter whether being stitched by pin in addition).Fiber can be natural or artificial source.They can be staple fiber or fibril or original place formation continuously.
In Fig. 1, through to the embossing applying adhesive so that the mode that width of cloth shape material glues together each other forms the lamination between first and second width of cloth shape material.Other laminations be can certainly adopt, machine printed, associating embossing (mechanical type), hot melt lamination or spray adhesive for example on whole surface or along the edge, carried out.In this embodiment, adhesive application unit 20 can be by other printing cell replacement.
Adhesive can be any adhesive that is generally used for lamination width of cloth shape material.If web materials is a tissue paper, then adhesive can be for example polyvinyl alcohol, carboxymethyl cellulose, ethylene vinyl acetate, polyvinyl acetate, ethylene acrylic, vinylacetate acrylic acid, styrene acrylic, polyurethane, polyvinylidene chloride, starch, converted starch, dextrin, water-soluble polymer is for example natural or synthetic rubber or plastics are suspended in latex and liliquoid in the water.If adopt another kind of width of cloth shape material, also should select to be suitable for its adhesive.Usually use a technical term " by gluing together ", it is not limited to the coating viscose glue, but can apply any adhesive.In the same manner, term " gummed " is used to applying adhesive.
Printing ink can be any printing ink that is normally used for width of cloth shape materials such as paper or non-woven fleece are carried out stamp.Printing ink should be fit to width of cloth shape properties of materials and the stamp process that is adopted.Can adopt any known stamp process.In a preferred embodiment, adopt the aniline stamp.
If adhesive is colored, then preferred adhesive can be dissolved each other mixed with color of ink mutually.Solvable mixing is not limited to printing ink and the mutual physical mixed of adhesive.Opposite term " solvable mixing " should be understood that how to be felt relevant with combined color in a broad sense.If color is miscible, the combined color of then feeling will have another shade that is different from original look, and this shade depends on the ratio of the color of mixing.This is a well-known principle from for example colour printed.If the employing multiple inks, then printing ink should mix each other and with adhesive is solvable.
For example on paper, carrying out in the process of 4 look stamps, adopting the alleged mixing method that loses lustre usually.Mass-tone is cyan, reddish violet, yellow and primary colours (being generally black).The mixing method that the loses lustre meaning is that the incident light selectivity is reflected.Through cyan, reddish violet, yellow and Neutral colour are mixed, can be perceived as the stamp on surface and to have the almost any color in colour triangle original.Do not need black in principle, because cyan, reddish violet and yellow combination will provide black or grey, but black is used to enhancing contrast ratio.Stamp black is than stamp cyan, reddish violet and yellow are more cheap up and down.For tissue paper, conventional stamp order at first be yellow, secondly be reddish violet, be cyan once more, be black at last.
When first width of cloth shape material 1 still was on first knurling rolls 4, other printing cell can be arranged between printing cell 10 and the adhesive application unit 20.In one embodiment, adopt three printing cells, it is adhesive application unit at the back.Then can adopt conventional 4 color stamps, in the color three kinds obtain applying as printing ink and the 4th kind of color obtains applying as colored adhesive.Alternatively, can adopt four printing cells and a kind of colourless adhesive.
